Polyhydroxyalkanoates and exopolysaccharides: An alternative for valuation of the co-production of microbial biopolymers.

Polyhydroxyalkanoates (PHAs) and exopolysaccharides (EPSs) belong to a class of abundant biopolymers produced by various fermenting microorganisms. These biocompounds have high value-added potential and can be produced concurrently. Co-production of PHAs and EPSs is a strategy employed by researchers to reduce costs associated with large-scale production.

Fibrinolytic enzyme from Arthrospira platensis cultivated in medium culture supplemented with corn steep liquor.

Artrhospira (Spirulina) platensis produced fibrinolytic enzyme under mixotrophic conditions using corn steep liquor (CSL). The enzyme was extracted, purified by combination of two chromatographic techniques and biochemically characterized. Maximum fibrinolytic production (268.
